Figure 18.31 shows a macroscopic view of a dielectric in a charged capacitor. Notice that the electric-field lines in the capacitor with the dielectric are spaced farther apart than the electric-field lines in the capacitor with no dielectric. This means that the electric field in the dielectric is weaker, so it stores less electrical potential

Acceleration by pulsed voltage accelerators is well described by the electrostatic approximation because the transit time of particles and the propagation time for electromagnetic waves in acceleration gaps are small compared to typical voltage pulslengths (∆ t 50 ns).
After being accelerated through a potential difference of 250 V, the ion enters a magnetic field of 0.5 T, in a direction perpendicular to the field. Calculate the radius of the path of the ion in the field. Example: A singly charged positive ion has a mass of 2.5 x 10-26 kg.
A particle experiencing circular motion due to a uniform magnetic field is termed to be in a cyclotron resonance. The term comes from the name of a cyclic particle accelerator called a cyclotron, showed in.
In summary, a question is posed about the motion of a conductor in a capacitor system with a uniform magnetic field. The acceleration of the conductor is found using Newton''s second law and the equation of capacitance. The conversation addresses the possibility of induced current flow and the role of the magnetic field and flux. The concept of dielectric
The electric field within capacitors is uniform and the field lines are parallel and equidistant from each other. The potential difference across a capacitor is directly proportional to the charge stored on it (V = Q/C) where ''V'' is voltage, ''Q'' is charge, and ''C'' is capacitance.
Let (Q) and (m) be the charge and mass of the particle, and (B_0) be the uniform magnetic field. Matching the cyclotron frequency to the frequency (f) of the voltage oscillations required for proper operations of the cyclotron.

A non-relativistic charged particle flies through the electric field of a cylindrical capacitor and gets into a uniform transverse magnetic field with induction B (Fig. 3.100). In the capacitor the particle moves along the arc of a circle, in the magnetic field, along a semi-circle of radius r.
The representation of magnetic fields by magnetic field lines is very useful in visualizing the strength and direction of the magnetic field. As shown in Figure (PageIndex{3}), each of these lines forms a closed loop, even if not shown by the constraints of the space available for the figure. The field lines emerge from the north pole (N), loop around to the south pole (S), and
